I have this in my .emacs which works in X mode.
(global-set-key [C-tab] 'next-multiframe-window)
I have tried to M-x global-set-key C-tab but only the TAB registers
which successfully remaps tab to 'next-multiframe-window

This is no doubt because your keyboard does not send C-<tab> to Emacs in terminal mode. That's normal. What you can do instead is bind a similar key, such as C-c TAB (or any other key sequence that your terminal recognizes) to the same command.
